Biological Soil Crust
You are walking through a sandy area favored by prickly pear cactus and rice grass, important food sources for the Fremont peoples as well as many animals. The sand is held in place by a lumpy covering called biological soil crust, which consists of cyanobacteria, lichens, green algae, mosses, and microfungi. In addition to soil stabilization, the crust retains moistures, acts as a seedbed, and supplies nitrogen to emerging plants. A single misplaced step can destroy this crust. Please stay on the trail.
